Adding a secondary audio track
1. Right-click the Secondary Audio/Video element in the Playlist tree and choose Add Secondary
Audio from the shortcut menu.
2. Select the Secondary Audio element in the Playlist tree and click the Browse button in the Control
Panel tab to choose an audio file.
Unlike the primary audio/video track, you can create a stand-alone secondary audio track that does not
have an associated secondary video track.
The process of adding segments is similar to the process for adding secondary video. There are two
exceptions:
n The secondary audio does not have a left and top position setting.
n The Secondary Video drop-down list allows you to associate the secondary audio track with an
existing secondary video track. When the tracks are associated, they become an interleaved sync
track when you compile your project. An audio track that is associated with a video track will mute
and unmute when the video track is turned on and off.
Secondary audio/video actions
You control the visibility of the secondary audio and video using actions. For more information, see
"Secondary audio/video actions" on page 118.
